ABSTRACT
The present contribution is devoted to the issue of monitoring of floor ice in the Great Hall and the
Small Hall cave by terrestrial laser scanning method combined with the method of electronic
tachymeter. This paper presents the results achieved in the second stage surveying work carried out for
the implementation the grant project VEGA No. 1/0786/10 „Research on the dynamics of the glacial
trappings and filling of the cave spaces by non-contact methods in terms of their safe and sustainable
utilization asa part of the natural heritage of Slovak republic" resolution of collective staff of the
Institute of Geodesy, Cartography and Geographic Information Systems Technical University of
Kosice Faculty of Mining, Ecology, Procces Control and Geotechnology. This problem, members of
the research team actively involved since 2010. The project was oriented as basic research to develop
effective non-destructive and non-contact measurement methods for monitoring changes in time and
spacetime filling ice cave spaces, followed by the creation of three-dimensional model cave. View of
the fact that the project research team plans to continue to do so in order to be the next stage in the
measurement area of the cave in the future based usable geodetic control consisting of geodetic points
located on the surface and underground, whose position is determined by the currently valid national
implementation JTSK 03 (Datum of Uniform Trigonometric Cadastral Network) and Baltic Vertical
Datum - After Adjustment.
INTRODUCTION
Under the decree of Ministry of Economy of the Slovak Republic no. 1/1993 from 20 July
1993 on mining measurement documentation during mining activities and other activities
carried this way, the provisions of decree apply to execution, keeping, completion and
preserving of mining measurement documentation of cave accessing works and the works of
keeping the caves in safe conditions. In the years 2010 and 2011, began deal with this
problem in an innovative project VEGA No. 1/0786/10 based on cooperation of the Institute
of Geodesy, Cartography and Geographic Information Systems, of Faculty BERG at the
Technical University of Końice with the Slovak Caves Administration Liptovský Mikuláń.
The main objective of the project was to digitally registering and exact modeling of changes
in the caves of ice filling the need for their protection and operation.
DOBŠINSKÁ ICE CAVE
The cave spaces, their sinter and ice filling impress the visitors both emotionally and
aesthetically. In Slovak Republic there are now more than 5500 caves known which are part
of country„s natural heritage. It is not only because of respect and admiration towards these
nature„s creations but also because of human natural attempt to discover the laws and
regularities of their morphogenetics and speleogenesis or demanding conditions their fauna
has to adapt to. All the mentioned above are the reasons for their thorough scientific research
aimed to know and conserve them for future generations. Advanced civilized society
features the interest in developing and protecting its natural heritage. Slovakia can be proud to
unique resources and beauty of caves since 44 out of the total number are declared as national
natural monuments. They are irreplaceable proof of live as well as inanimate part of nature
